Carbon Ion Beam Radiotherapy for Sinonasal Malignant Tumors Invading Skull Base

Figure 1

A case of 43-year-old Japanese female with adenoid cystic carcinoma in skull base. Axial, coronal, and sagittal contrast T1-weighted magnetic resonance image before carbon ion beam radiotherapy shows marginal enhancement and surrounding edema; dose distribution of carbon ion radiotherapy in axial CT image and axial contrast-enhanced T1-weighted magnetic resonance image 32 months after carbon ion beam radiotherapy show enhancement and edema in the right temporal lobe. This patient received no treatment for cerebral radiation injury. CIRT: carbon ion beam radiotherapy.
